Joint swelling symptoms
Swelling of any kind is the result of a buildup of fluid within soft tissue. When there is swelling in a joint, or joint effusion, it is either the surrounding tissue or the tissue lining the inside of the joint that swells — not the joint itself, which is made of bone and cartilage.
The swelling is most often secondary to trauma and only involves the joint that has been injured. However, if there has been no injury and more than one joint is swollen, it suggests there is some sort of systemic illness causing the swelling.
Common characteristics of joint swelling
If you're experiencing joint swelling, you are likely to also experience:
- The swollen joint may or may not be painful
- The joint will appear misshapen and enlarged
- There is often joint stiffness: This will likely cause difficulty flexing or moving the joint.
- There may be redness and heat over and around the swollen joint: Fever may also be present.
- There may be rash, fever, fatigue, and weight loss
Duration of symptoms
Symptoms of joint swelling may be more temporary or persistent, again, depending on the cause.
- Temporary: Swelling from a mild injury may resolve simply with rest.
- Persistent: Most forms of joint swelling, especially if infection is involved, will not heal on their own and can get progressively worse if not treated.
Who is most often affected by joint swelling symptoms
The following people are more likely to experience joint swelling.
- Athletes: This is often a sports injury. Acute trauma occurs due to being struck during play. Chronic wear and tear of a joint's cartilage occurs over time due to overuse.
- Anyone involved in a motor vehicle accident
- Anyone with one of several types of autoimmune illnesses: These conditions cause the body's immune system to attack its own healthy tissue, including the soft tissues in and around the joints.
When joint swelling symptoms are most likely to occur
Joint swelling is more likely at these times:
- The morning: Swelling and stiffness due to an inflammatory process will be especially noticeable in the morning.
- After exercise: Swelling and stiffness caused by wearing away of a joint's cartilage will be worse following exercise.
Are joint swelling symptoms serious?
The severity of joint swelling will ultimately be determined by the cause.
- Not serious: Mild swelling following a minor injury is rarely serious, especially if the swelling goes down with rest and an ice pack.
- Moderately serious: Persistent swelling that does not respond to rest, heat, ice, or non-steroidal anti-inflammatory drugs should be seen by a medical provider at the first opportunity.
- Serious: Hot, swollen, painful joints must be treated right away in order to prevent further damage to the bone, cartilage, and lining of the joint.
Joint swelling causes
The following can result in swelling of the soft tissue around the joint.
- Fracture of a bone within the joint
- Dislocation of the parts of the joint
- Sprain: This is an over-stretching of the ligaments which hold the bones of a joint together.
- Strain: This is an over-stretching of the tendons which attach muscles to bones.
- Surgery on or near the joint
- Wear and tear: Damage and wear to the cartilage at the ends of the bones, due to overuse for a long period of time.
Swelling of the synovium, the inner lining of the joint, can be caused by the following. This lining swells due to inflammation and this inflammatory process causes the lining's fluid to increase, causing further swelling around the joint.
- Autoimmune diseases: These can cause joint damage, joint swelling, and flu-like symptoms.
- Autoimmune skin disorders that also affect the joints: These may cause thickened, tightened skin, or skin that is very red with heavy patches of silvery scales.
If the tissue in and around the joint becomes infected, this can lead to pain and swelling.
- Injury: Any injury that reaches to the inside of the joint — usually a puncture wound — can introduce bacteria that will cause swelling, severe pain, and redness over the joint.
- Damage from autoimmune disease: A joint damaged by an autoimmune disease can also become infected by bacteria, viruses, or fungus.
Crystalline deposits in the joints
Crystalline deposits can build up in the joints, especially the smaller ones. This may be caused by a combination of the following:
- Poor diet
- Drinking alcohol
- Chronic dehydration
- The use of diuretics
Arthritis simply means inflammation of the joints. Because the feet and ankles have many small joints and carry the weight of the body, they are often the first place that arthritis appears.
Arthritis is caused by a breakdown in the protective cartilage at the end of each joint, so that the bones begin to wear against each other and the joint becomes stiff and painful. This breakdown may be due to simple wear and tear; an injury; or from rheumatoid arthritis, an autoimmune condition which causes the body to break down its own cartilage.
Symptoms include swelling, warmth, and redness in the joint, and pain with movement or with pressure on the joint.
Diagnosis is made through patient history, physical examination, and imaging such as x-rays, CT scan, or MRI.
There is no cure for arthritis, but treatment is important because the symptoms can be managed to prevent further damage, ease pain, and improve quality of life. Treatment involves physical therapy, pain-relieving medications, and sometimes surgery to help repair damaged joints.
Top Symptoms: swollen ankle, swollen foot, joint stiffness, pain in one ankle, ankle stiffness
Mild/moderate hip arthritis
Arthritis of the hip is inflammation of one or more of the joints in the hip. Pain, swelling, and stiffness are the primary symptoms of arthritis. Hip arthritis can make it hard to do many everyday activities, such as walking or climbing stairs. It is a major cause of lost work time and a serious disability for many people.
Top Symptoms: hip pain, difficulty walking, pain in one hip, limping, groin pain
Symptoms that always occur with mild/moderate hip arthritis: hip pain
Symptoms that never occur with mild/moderate hip arthritis: severe hip pain
Urgency: Primary care doctor
Arthritis is inflammation of one or more of the joints. Pain, swelling, and stiffness are the primary symptoms of arthritis. Any joint in the body may be affected by the disease, but it is particularly common in the knee.
Top Symptoms: pain in both knees, knee stiffness, knee instability, swollen knee, morning joint stiffness
Symptoms that always occur with knee arthritis: pain in both knees
Urgency: Primary care doctor
Lower back arthritis
Osteoarthritis, most often simply called arthritis, is a disease of cartilage. In joints, where bones touch and move against one another, cartilage helps provide lubrication for smooth movement, and acts as a shock absorber. Cartilage is also present in between vertebrae, which are the bones comprising the spine. Osteoarthritis of the spine, also known as degenerative joint disease, happens when the cartilage between vertebrae dries out and shrinks. The vertebrae are thus not as able to move smoothly against one another. The ability to walk and perform normal daily activities can be impaired due to inflammation and pain in the lower back.
Top Symptoms: lower back pain, spontaneous back pain, back pain that gets worse when straightening it, back pain from overuse

Shoulder arthritis is inflammation of the shoulder joint, where the upper arm bone (humerus) meets the shoulder blade (scapula) and collarbone (clavicle). This inflammation can be caused by osteoarthritis or "wear-and-tear," injury to the shoulder joints, rotator cuff injuries, or r...
Lyme disease is a bacterial illness transmitted through the bite of the deer tick (black-legged tick) after it has been attached for at least 36-48 hours. These may be tiny, immature ticks that are difficult to see, often attaching in a place on the body where hair grows.
The disease does not spread through casual contact, either between humans or between humans and pets.
Early symptoms include fever, chills, headache, and body aches. There may be a rash around the tick bite, which sometimes enlarges to form a clear circle around the bite.
Later symptoms are severe with headaches, neck stiffness, further rashes, facial drooping (palsy,) and joint pain and swelling. This is a medical emergency. Take the patient to the emergency room or call 9-1-1.
Untreated Lyme disease in a pregnant woman can lead to stillbirth, but antibiotics will usually prevent this.
Diagnosis is made through symptoms as well as a blood test.
Treatment consists of oral antibiotics in most cases, though severe cases may require IV antibiotics.
Rarity: Ultra rare
Top Symptoms: fatigue, headache, irritability, muscle aches, loss of appetite
Urgency: Primary care doctor

Psoriatic arthritis is a condition which causes inflammation of the joints. In most circumstances, psoriatic arthritis presents between the ages of 30 and 50 years and occurs after the manifestation of the symptoms of psoriasis, which is a disease of the skin. Psoriatic arthritis...
A cyst is a small sac or lump, filled with fluid, air, fat, or other material, that begins to grow somewhere in the body for no apparent reason. A skin cyst is one that forms just beneath the skin.
It's believed that skin cysts form around trapped keratin cells – the cells that form the relatively tough outer layer of the skin.
These cysts are not contagious.
Anyone can get a skin cyst, but they are most common in those who are over age 18, have acne, or have injured the skin.
Symptoms include the appearance of a small, rounded lump under the skin. Cysts are normally painless unless infected, when they will be reddened and sore and contain pus.
Diagnosis is made through physical examination. A small cyst can be left alone, though if it is unsightly or large enough to interfere with movement it can be removed in a simple procedure done in a doctor's office. An infected cyst must be treated so that the infection does not spread.
Top Symptoms: skin-colored armpit bump, marble sized armpit lump, small armpit lump
Symptoms that always occur with skin cyst: skin-colored armpit bump
Urgency: Wait and watch
Synovial chondromatosis is a disease affecting the synovium, which is a thin flexible membrane around a joint. It can often be confused with tendinitis and/or arthritis.
Rarity: Ultra rare
Top Symptoms: joint swelling, pain in one knee, pain in one hip, swollen knee, spontaneous knee pain
Symptoms that always occur with synovial chondromatosis: joint swelling
Symptoms that never occur with synovial chondromatosis: fever, night sweats, unintentional weight loss, warm red ankle swelling, warm red knee swelling, warm and red elbow swelling

Joint swelling treatments and relief
You can try the following joint swelling remedies at home.
- Elevate the joint: Raise the joint above the level of your heart by propping up the arm or leg on pillows.
- Use ice or heat: Apply ice packs or hot packs to the painful, swollen joints, depending on which is more effective.
- NSAIDs: Take over-the-counter non-steroidal anti-inflammatory drugs such as ibuprofen (Advil, Motrin), naproxen (Aleve), or aspirin, to help reduce pain and swelling.
When to see a doctor
You should see your doctor to address the following.
- Persistent joint swelling following a mild to moderate injury: This means the swelling has not gone down after two to three days.
- Swelling that occurs for no apparent reason
- Swelling that occurs in the presence of other symptoms of illness: Such as fever or body aches
- Physical therapy: This may be recommended once an injured joint is ready to heal.
When it is an emergency
Seek immediate swollen joint treatment in the emergency room or call 911 if:
- You have a fever and multiple swollen joints
- Worsening injury: Any acute injury to a joint with rapid swelling, deformity, and pain should be addressed immediately.
